Graph each line using intercepts 1/4 x + 2y =2

Leno4ka [110]

The given equation is,

$\frac{1}{4}x+2y=2$

It can be rewritten in the form of y=mx+c, where c is the y intercept.

Hence,

$\begin{gathered} 2y=-\frac{1}{4}x+2 \\ y=\frac{-1}{4\times2}x+\frac{2}{2} \\ y=\frac{-1}{8}x+1 \end{gathered}$

Put different values for x and find value of y.

When x=0, y=1.

When x=1,

$y=\frac{-1}{8}+1=\frac{7}{8}$

The graph is,

I have the question in a screengrab. Thank you, whoever helps me.

To simplify

$\sqrt[4]{\dfrac{24x^6y}{128x^4y^5}}$

we need to use the fact that

$\sqrt[4]{x^4}=|x|$

Why the absolute value? It's because $(-x)^4=(-1)^4x^4=x^4$ .

We start by rewriting as

$\sqrt[4]{\dfrac{2^23x^6y}{2^6x^4y^5}}$

$\sqrt[4]{\dfrac{2^23x^4x^2y}{2^42^2x^4y^4y}}$

Since $x\neq0$ , we have $\dfrac xx=1$ , and the above reduces to

$\sqrt[4]{\dfrac{3x^2y}{2^4y^4y}}$

Then we pull out any 4th powers under the radical, and simplify everything we can:

$\dfrac1{\sqrt[4]{2^4y^4}}\sqrt[4]{\dfrac{3x^2y}{y}}$

$\dfrac1{|2y|}\sqrt[4]{3x^2}$

where $y>0$ allows us to write $\dfrac yy=1$ , and this also means that $|y|=y$ . So we end up with

$\dfrac{\sqrt[4]{3x^2}}{2y}$

making the last option the correct answer.

Given that e= 2i – 5j + 9k and f= 8i + 15j + k, find 3f – 2e.

ipn [44]

Plug in "8i + 15j + k" for "f", and "2i – 5j + 9k" for "e"

3(8i + 15j + k) - 2(2i – 5j + 9k)

Distribute 3 to (8i + 15j + k) & - 2 to (2i – 5j + 9k)

3(8i + 15j + k) = 24i + 45j + 3k

-2(2i - 5j + 9k) = -4i + 10j - 18k

-------------------------------------------------------------------------------------------------------------------

Simplify. Combine like terms

24i - 4i + 45j + 10j + 3k - 18k

(24i - 4i) + (45j + 10j) + (3k - 18k)

20i + 55j - 15k is your answer, or (C)

What is the equation in slope-intercept form of a line that passes through the points (5,3) (4,-3)

Darya [45]

Answer:

y=6x-27

Step-by-step explanation:

To find the slope of a line given 2 points; use this equation.

$\frac{y_2-y_1}{x_2-x_1} = \frac{rise}{run}$

(5,3) (4,-3)

$x_1 y_1$ $\\x_2 y_2\\\\$

$\frac{3 - (-3)}{4-5} =\frac{-6}{-1} = 6$

slope = 6
